Update Failed - Bernina B 590 Service And Maintenance Manual

3.8 Update failed

Issue:
Updating the machine has failed and update cannot be executed.
A new firmware version might be required for various reasons.
Case 1: Bootloader out of date:
Typically occurs with machines from early production, or when several updates have been skipped.
1. Start normal customer updating process.
2. After rebooting, the black screen with the red BERNINA logo stays, or keeps reappearing.
3. Switch machine off. Connect USB stick containing the relevant firmware for machine. Load firmware
from USB stick (see 8.2).
4. Update can be fully loaded in this way. If an older firmware version is on the machine, it is
recommended (for safety reasons) to install the bootloader (xbxxxxxx.B5xxx.bin) first, and only then
the application and data. This means that only the bootloader is loaded on a FAT32 formated data
stick and then installed on the machine. After that, fully update the machine.
5. Rebooting the machine after updating via alternative access (USB stick) must always be carried out
manually: OFF/ON.
Important! Updating via alternative access deletes all customer data!
Case 2: EEPROM needs replacing
The EEPROM doesn't work for unknown reasons, and must be replaced. The machine will ask for a
firmware in any case.
1. Machine is switched off.
2. Connect USB data stick containing the relevant firmware for machine.
3. Switch machine on. Firmware updating process starts automatically.
4. Reboot manually.
5. Start machine in Service Program. Carry out the required calibrations:
Calibration
Enter series number as prompted
Upper-thread tension unit
Presser-foot height light barrier (micro switch)
Start/Stop Unit (SSU)
Button length measuring system (buttonhole calibration)
Electronic balance calibration
Case 3: Replacing a PCBA-Base
The EEPROM has been removed from faulty PCBA-Base and attached to the new one.
1. Machine is switched off.
2. Connect USB data stick containing the relevant firmware for machine.
3. Switch machine on. Firmware updating process starts automatically.
4. Reboot manually.
5. The use of the previous EEPROM makes recalibration unnecessary since all relevant data is saved on
it. Checking the data in Service Program, however, is strongly recommended.
Case 4: EEPROM has been replaced, but the loaded machine recognition is wrong.
For unknown reasons, the EEPROM used has already machine recognition, but it is unknown.
The EEPROM counts as 'master'. In this case, the EEPROM must be replaced with a new one, as in Case 2.
